Maxime Ripard 5d93dad67d drm/vc4: hdmi: Take into account the clock doubling flag in atomic_check 
[ Upstream commit 320e84dc61 ]

Commit 63495f6b4a ("drm/vc4: hdmi: Make sure our clock rate is within
limits") was intended to compute the pixel rate to make sure we remain
within the boundaries of what the hardware can provide.

However, unlike what mode_valid was checking for, we forgot to take
into account the clock doubling flag that can be set for modes. Let's
honor that flag if it's there.
